Abstract

An information transmission method, a first device, a second device, a chip, a computer readable storage medium, a computer program product, a computer program, and a communication system are provided. The method includes: a first device sends first information. The first information is used for indicating N device identifiers. A second device receiving the first information sends request information for a channel resource when the N device identifiers include a device identifier of the second device, and N is an integer greater than or equal to 2.

1 . A method for information transmission, comprising:
 sending, by a first device, first information, wherein the first information is used to indicate N device identifiers, so that a second device that receives the first information sends request information for a channel resource in a case that the N device identifiers comprise a device identifier of the second device, and Nis an integer greater than or equal to 2.   
     
     
         2 . The method of  claim 1 , wherein the first device is an access point (AP) or a station (STA), and the second device is a zero-power terminal associated with the first device. 
     
     
         3 . The method of  claim 1 , wherein the channel resource is transmission opportunity(s) (TXOP(s)) obtained by the first device through channel access. 
     
     
         4 . The method of  claim 1 , further comprising:
 in the case that the N device identifiers comprise the device identifier of the second device, receiving, by the first device, the request information from the second device on a first time unit, wherein the first time unit is related to the N device identifiers, wherein the method further comprises:   in a case that the request information is received by the first device, determining, by the first device, that the second device requests the channel resource.   
     
     
         5 . A first device, comprising: a processor and memory, wherein the memory is configured to store a computer program and a processor is configured to invoke and execute the computer program stored in the memory to cause the first device to perform:
 sending, by a first device, first information, wherein the first information is used to indicate N device identifiers, so that a second device that receives the first information sends request information for a channel resource in a case that the N device identifiers comprise a device identifier of the second device, and Nis an integer greater than or equal to 2.   
     
     
         6 . The first device of  claim 5 , wherein the processor is further configured to invoke and execute the computer program stored in the memory to cause the first device to perform:
 sending second information, wherein the second information comprises M pieces of grant information respectively corresponding to M devices, each of the M pieces of grant information is used to indicate whether a channel resource is allocated for a device corresponding to the grant information, and M is an integer greater than or equal to 1.   
     
     
         7 . The first device of  claim 6 , wherein the second information is determined based on at least one piece of request information received by the first device. 
     
     
         8 . The first device of  claim 6 , wherein the M devices comprise devices requesting channel resources. 
     
     
         9 . The first device of  claim 6 , wherein the M devices comprise N devices. 
     
     
         10 . The first device of  claim 5 , wherein in a case that the second information indicates that the channel resource is allocated for the second device, the channel resource is used for information transmission between the second device and the first device, or information transmission between the second device and a third device. 
     
     
         11 . The first device of  claim 10 , wherein the information transmission comprises sending data by the second device and receiving acknowledgement (ACK) information for the data by the second device. 
     
     
         12 . A second device, a processor and memory, wherein the memory is configured to store a computer program and a processor is configured to invoke and execute the computer program stored in the memory to cause the second device to perform:
 receiving first information sent by a first device, wherein the first information is used to indicate N device identifiers; and send request information for a channel resource in a case that the N device identifiers comprise a device identifier of the second device, wherein N is an integer greater than or equal to 2.   
     
     
         13 . The second device of  claim 12 , wherein the first device is an access point (AP) or a station (STA), and the second device is a zero-power terminal associated with the first device. 
     
     
         14 . The second device of  claim 12 , wherein the channel resource is transmission opportunity(s) (TXOP(s)) obtained by the first device through channel access. 
     
     
         15 . The second device of  claim 12 , wherein the processor is configured to invoke and execute the computer program stored in the memory to cause the second device to perform:
 receiving second information, wherein the second information comprises M pieces of grant information respectively corresponding to M devices, each of the M pieces of grant information is used to indicate whether a channel resource is allocated for a device corresponding to the grant information, and M is an integer greater than or equal to 1.   
     
     
         16 . The second device of  claim 15 , wherein the second information is determined based on at least one piece of request information received by the first device. 
     
     
         17 . The second device of  claim 15 , wherein the M devices comprise devices requesting channel resources 
     
     
         18 . The second device of  claim 15 , wherein the M devices comprise N devices.
